Problems solved by technology

The disadvantage is that the carbon fiber plastic produced by the traditional process has a high filling content of carbon fiber, which leads to poor fluidity of the composite material, affects the appearance of the product, and causes certain wear and tear on the processing equipment, and the carbon fiber plastic sheet produced is not stable. Smoothness and color uniformity are not ideal

Embodiment 1

[0035]Embodiment 1: The technical solution of the present invention relates to a kind of bamboo scrap waste regenerated composite plastic board, and its composition comprises the raw material of following weight ratio: 100 parts of waste PVC powder, 20-30 parts of bamboo scrap powder, composite stabilizer 5- 7 parts, processing aid ACR 3-5 parts, impact modifier CPE 5-8 parts, lubricant 0.8-1 part, filler 8-10 parts, colorant 0.1-0.2 parts, anti-ultraviolet agent 0.01-0.015 parts share.

[0036] The composite stabilizer refers to the mixture of tri-salt, di-salt and metal soap in the reaction system with nascent grain size and various lubricants by using the symbiotic reaction technology, and the processing aid refers to the acrylic acid series Resin, impact modifier refers to chlorinated polyethylene, lubricant refers to paraffin and stearic acid, filler refers to CaCO 3 , the coloring agent refers to a pigment, and the anti-ultraviolet agent refers to 2-hydroxy-4-methoxyben...

Embodiment 2

[0037] Embodiment 2: The operation steps of the method invention of improving the color and luster of bamboo scrap waste regenerated composite plastic board are as follows:

[0038] (1) Sorting, crushing, cleaning and milling the waste PVC material and bamboo powder at first, adding bleaching powder, dilute hydrochloric acid and other medicaments to the milled powder to fade the color;

[0039] (2) Send the faded powder to a magnetic stirrer and add azodicarbonamide for pretreatment before modification;

[0040] (3) The pretreated powder is then passed through the "secondary stirring device", adding aluminate coupling agent and butyl acrylate coupling agent to carry out molecular modification of PVC;

[0041] (4) PVC powder particles enter the granulator through the discharge pipe, add colorants and processing aids, knead, homogenize, and granulate;

[0042] (5) After granulation, it is transported to the feeder in the molding workshop through the transmission channel, and en...

Embodiment 3

[0044] Embodiment three: the method invention of improving the surface smoothness of bamboo scrap waste regeneration composite plastic plate is as follows:

[0045] Firstly, the waste PVC material and bamboo powder are sorted, crushed, cleaned, and pulverized, and then include:

[0046] (1) Transport the grinding powder to the suspension reaction kettle through the belt, add azodicarbonamide, dilute hydrochloric acid, etc. to stir and react, and adjust the stirring intensity to control the particle size and particle size distribution of PVC, and form the PVC molecule on the particle surface. The coating film makes the PVC resin particles regular in shape and uniform in particle size;

[0047] (2) The PVC slurry directly enters the stripping tower through the discharge port of the reaction kettle. After the azodicarbonamide substance in the PVC particles is removed, it is sent to the drying tower for centrifugal dehydration through a conveyor belt, and then conveyed by a screw ...

Abstract

The invention relates to a bamboo shred waste regenerated composite plastic plate and a production technology thereof. Waste and old PVC (polyvinyl chloride) wastes and bamboo shreds, which are raw materials, are classified, fragmented, cleaned, dried, milled, pretreated, and molecule-modified to obtain the bamboo shred waste regenerated composite plastic plate. The technology has the advantages of no pollutant generation and low energy consumption in the whole production process, and low price and stable quality of the produced regenerated composite plastic plate.

Description

technical field [0001] The invention relates to a composite plastic board and its production process, in particular to a regenerated composite plastic board using waste PVC and bamboo chips as raw materials and its production process. Background technique [0002] At present, the raw material PVC used in my country's doors and windows and other building materials is mainly produced by petroleum cracking, which consumes a lot of oil. At the same time, nearly one million tons of these plastics produced will be converted into waste plastics every year, and the waste plastics will be recycled and made into high-performance products. plastics is only about 15%, which is far lower than the recovery rate of waste plastics in developed countries (above 50%), and the plastics recycled in my country are mainly used to make drainage pipes and sewer pipes with lower performance requirements, and are rarely used in Preparation of high-quality carbon fiber recycled composite plastic board. ...
